Chapter 3 Personality and Values
The Big Five Model In contrast to the MBTI, the five-factor model of personality— more typically called the Big Five—has received strong supporting evidence. An impressive body of research, accumulated in recent years, supports that five basic dimensions underlie all others and encompass most of the significant variation in human personality.3 The following are the Big Five factors:
■
Extroversion—This dimension captures one’s comfort level with relationships.
Extroverts tend to be gregarious, assertive, and sociable. Introverts tend to be reserved, timid, and quiet.
■
Agreeableness—This dimension refers to an individual’s propensity to defer to others. Highly agreeable people are cooperative, warm, and trusting. People who score low on agreeableness are cold, disagreeable, and antagonistic.
■
Conscientiousness—This dimension is a measure of reliability. A highly conscientious person is responsible, organized, dependable, and persistent. Those who score low on this dimension are easily distracted, disorganized, and unreliable.
■
Emotional stability (often labeled by its converse, neuroticism)—This dimension taps a person’s ability to withstand stress. People with positive emotional stability tend to be calm, self-confident, and secure. Those with high negative scores tend to be nervous, anxious, depressed, and insecure.
